C1 Connections designs and delivers certified connections for on- and off-shore substructures and other tailored solutions.

Our in-house design capabilities allow us to make (concept) designs very efficiently for even the most demanding connections. Thousands of hours testing have provided us the key insights to deliver robust designs.

Our development, the C1 Wedge Connection, outperforms alternative connections. When compared to conventional bolted connections the C1 Wedge Connection delivers a higher ultimate capacity, fatigue resistance while allowing HSE compliant installation.

C1 Connections can supply both fasteners as well as entire connections.
